Anhydrous crystalline or crystalline hemihydrate monohydrate or

A solid electrolyte having high electron conductivity and high oxide ion conductivity, which is composed of a sintered body consisting substantially of (a) an oxide of cobalt, (b) an oxide of at least one metal selected from strontium and lanthanum, and (c) an oxide of at least one metal selected from bismuth and cerium. This solid electrolyte is useful for selectively separating oxygen from a gaseous atmosphere having a high oxygen partial pressure into a gaseous atmosphere having a low oxygen partial pressure.

Oxygen scavenger composition, heat-generating composition and

A process for preparing amino alcohols, which comprises reacting a polyhydric alcohol containing at least one primary alcoholic hydroxyl group and at least one secondary alcoholic hydroxyl group and expressed by the following general formula ##STR1## wherein R.sup.1 is an alkyl group, R.sup.2 and R.sup.3 are identical or different and represent a hydrogen atom or a lower alkyl group an n is an integer of 0 to 3, With ammonia in the presence of specified hydrogenation catalyst thereby to aminate the secondary alcoholic hydroxyl group of the polyhydric alcohol selectively.

Process for preparing amino alcohols

An inclusion complex compound comprising (a) meta-cyclophane and (b) a trans-terpenoid of the formula ##STR1## wherein n is an integer of 1 to 9; A.sub.1 and A.sub.2 each represent (1) a hydrogen atom, (2) a halogen atom, (3) an inorganic group containing an oxygen, nitrogen or sulfur atom, (4) an organic group containing 1 to 5 carbon atoms, or (5) an organic group containing an oxygen, nitrogen or sulfur atom and 1 to 5 carbon atoms; and C* is the carbon atom of a carbonyl or methylene group, Included by the meta-cyclophane. This inclusion complex compound can be prepared by contacting the meta-cyclophane with a mixture containing the trans-terpenoid. A trans-terpenoid can be separated from a mixture containing it by utilizing an inclusion complex compound of it with meta-cyclophane.
